Multi-row brassica juncea combine harvester

Abstract

The invention belongs to the technical field of agricultural machinery and relates to a multi-row brassica juncea combine harvester. The multi-row brassica juncea combine harvester comprises a frame and a power transmission mechanism, the frame is arranged on a tracked chassis and supports a leaf clamping, lifting and conveying mechanism, a root cutting mechanism and a leaf cutting mechanism, andthe root cutting mechanism and the leaf cutting mechanism are arranged at front and rear ends of the leaf clamping, lifting and conveying mechanism which comprises at least two pairs of inside clamping loop conveying belts. Each loop conveying belt comprises a wheel carrier extending along a conveying direction, supporting belt pulleys available for position adjusting and positioning are mounted at front and rear ends of each wheel carrier, one ends of wheel arms are supported and hinged at intervals to each wheel carrier along the length direction, and tensioning belt pulleys in tendency to aclamping direction are mounted at the other ends of the wheel arms. V-shaped belts surround the supporting belt pulleys and the tensioning belt pulleys, and the supporting belt pulleys at front endsof the wheel carriers and the V-shaped belts at the tensioning belt pulleys form correction slopes. The multi-row brassica juncea combine harvester has advantages that a series of problems including root cutting, conveying, leaf removing and the like in brassica juncea harvesting are well solved, accurate root cutting and lossless conveying can be realized, and accordingly mechanical harvesting quality is guaranteed.

Description

technical field [0001] The invention relates to a harvester of soil surface knot vegetables with stems and leaves, in particular to a multi-row combine harvester of green cabbage heads, which belongs to the technical field of agricultural machinery. Background technique [0002] The scientific name of green cabbage head is stem tumor mustard, which is the main raw material for making Fuling mustard. For a long time, the harvest of green cabbage has been dominated by manual harvesting, which has high labor intensity and low work efficiency, which has seriously affected the yield, quality and economic benefits of pickled mustard. [0003] It can be seen from the search that a Chinese patent document with application number 201910252863.0 proposes a green vegetable head harvester, including a harvesting mechanism for harvesting green vegetable heads, a self-propelled chassis with a loading box, and a self-propelled chassis for connecting the and the harvesting mechanism and a ...

AI Technical Summary

Problems solved by technology

To sum up, none of the existing technologies can properly solve the problems of root cutting, transportation, cutting of stems and leaves and separation of tumor-like stems when the head of cabbage is harvested.

Moreover, no matter whether the overall height of the header is adjusted by the suspension adjustment mechanism or the height adjustment rod, for multi-row (2 rows and above) harvesting, when the root cutting height of the cabbage heads in each row is inconsistent, the independent adjustment of the height of each row cannot be realized. Cutting height, it is difficult to ensure the quality of root cutting
